Abstract

Purpose

In this study, a railway superstructure is modeled with a new approach called locally continuous supporting, and its behavior under the effect of moving load is analyzed by using analytical and numerical techniques. The purpose of the study is to demonstrate the success of the new modeling technique.

Design/methodology/approach

In the railway superstructure, the support zones are not modeled with discrete spring-damping elements. Instead of this, it is considered to be a continuous viscoelastic structure in the local areas. To model this approach, the governing partial differential equations are derived by Hamilton’s principle and spatially discretized by the Galerkin’s method, and the time integration of the resulting ordinary differential equation system is carried out by the Newmark–Beta method.

Findings

Both the proposed model and the solution technique are verified against conventional one-dimensional and three-dimensional finite element models for a specific case, and a very good agreement between the results is observed. The effects of geometric, structural, and loading parameters such as rail-pad length, rail-pad stiffness, rail-pad damping ratio, the gap between rail pads and vehicle speed on the dynamic response of railway superstructure are investigated in detail.

Originality/value

There are mainly two approaches to the modeling of rail pads. The first approach considers them as a single spring-damper connected in parallel located at the centroid of the rail pad. The second one divides the rail pad into several parts, with each of part represented by an equivalent spring-damper system. To obtain realistic results with minimum CPU time for the dynamic response of railway superstructure, the rail pads are modeled as continuous linearly viscoelastic local supports. The mechanical model of viscoelastic material is considered as a spring and damper connected in parallel.

Abstract

Purpose

This study aims to examine the current state of the research activities of scholars in the hospitality and tourism field by analyzing the first 20 years of the new millennium.

Design/methodology/approach

Longitudinal analyses using 14,229 journal articles as data source were realized by adopting BibExcel, Gephi and VOSviewer network analysis software packages.

Findings

This study provides a comprehensive overview of the hospitality and tourism research based on authorship and social network analysis, with patterns of prolific authors compared over four distinct periods.

Research limitations/implications

The hospitality and tourism academic society is clearly illustrated by tracing academic publication activities across 20 years in the new millennium. In addition, this study provides a guide for scholars to search for multidisciplinary collaboration opportunities. Government agencies and non-governmental organisations can also benefit from this study by identifying appropriate review panel members when making decisions about hospitality- and tourism-related proposals.

Originality/value

To the best of authors’ knowledge, this study is the first to use bibliometric analysis in assessing research published in leading hospitality and tourism journals across the four breakout periods in the new millennium.

Abstract

Purpose

The study presents the push–pull motives and behavioural intentions of youth tourists and how these provide the foundation for the planning and development of Ghana’s tourism future. Since youth tourism (YT) is regarded as a niche market globally, the purpose of this paper is to identify the prospects of this form of tourism in a developing nation.

Design/methodology/approach

The study has utilised a convenience sampling approach in gathering data from 557 youth tourists, adapting existing instruments for measuring push–pull motives, satisfaction and behavioural intentions. The reliability and validity of the instruments were established through confirmatory factor analysis, exploratory factor analysis and Cronbach’s α analyses. Structural equation modelling is used to establish relationships.

Findings

The results revealed the positive effects of push and pull factors on tourists’ satisfaction as well as the significant influence of tourists’ satisfaction on youth behavioural intentions. However, push factors positively influenced pull factors of youth tourists.

Research limitations/implications

The conclusion and recommendations of this study might not be congruent with the factors that motivate adults or student tourism, satisfaction and behavioural intentions.

Practical implications

The findings of the research validate the viability of YT activities and the behavioural intentions for future tourism market in Ghana. Ghana’s tourism sector should design interesting and competitive offers that attract youth tourists and address tourism growth.

Originality/value

To date, investigation into motives, satisfaction and behavioural intentions of youth tourists as the basis for future tourism development remains a virgin field in Ghana. This study has timely attempted to address this gap.
